Thrust Washer
-
Seamlessly connect trailer to Dolly!
The Thrust Washer is an optional Adapter designed for trailers with step-down hitches/lips and is included with all Ball Mount adapters. See Instruction Manual for details.
The Puzzle Piece
The Puzzle Piece can be inserted to increase the height of the Ball Mount to provide more surface area while tightening or removed to bypass any protrusions on the hitch.
The Atwood Adapters
Have a Jayco Trailer with an Atwood Hitch? Switch out the Puzzle Piece for one of our Atwood Adapters for our most secure connection to date!
What does a proper connection look like?
STANDARD CONNECTION
A flush, tight connection between the ball mount and coupler. Flat, without any visible gaps. A Thrust Washer is NOT required for this type of connection, but can be used to increase the connection height OR increase tightening surface area for a more secure connection:
CONNECTION WITH THRUST WASHER
Required when protrusions on the trailer coupler prevent a flush, flat connection. Simply remove the Puzzle Piece to bypass them:

Which trailer dolly is right for me?
To choose the best parking solution for your trailer, you'll need to know:
- Your trailer's gross weight (GVWR) and tongue weight
- Your trailer's coupler style, including its height from the ground
- The types of terrain you'll be moving on (including grade %)
- If you'd prefer manual, electric or wireless operation
Compare these details to our trailer dollies and accessories, or contact us.

Does each trailer dolly come with everything I need?
Yes! Each trailer dolly includes a hitch adapter that's compatible with most ball mount trailer couplers. See the Transformer, Carrier or Accessories page for additional connections. All electric models include batteries, charging cables, hardware and built-in safety features so you can park with confidence.
What is the difference between gross weight and dry weight?
GVWR (Gross Vehicle Weight Rating) includes the capacity of your trailer (how much you can put in it, including passengers). This is different from the dry weight, or unloaded vehicle weight (UVW), which is the weight of your trailer when empty.
What is trailer tongue weight? Why does it matter?
Tongue weight is the downward force that the trailer tongue applies to the hitch when connected to the trailer dolly. Using your Parkit360 for a trailer with too much or too little tongue weight could make moving and steering difficult, or cause issues with traction. We recommend that your tongue weight be 10% of your trailer's gross weight (GVWR), although this may vary for smaller trailers.
